Unable To View Any Videos in Firefox

Firefox is not playing any videos on my device. Will typically 'spin' as if loading.

Every site repeats the same stupid troubleshooting steps. I have already: Cleared cookies and cache, Disabled all themes and extensions, Tried in troubleshooting mode, Disabled hardware acceleration, 'refreshed' Firefox, Did a complete uninstall, including deleting %APPDATA%\Mozilla\ and reinstalled.

Videos play just fine in other browsers, like Google Chrome

Running Firefox 97.0.1 (Up to date) on Windows 10, Version 21H2

Is that the screenshot you meant to post, Jonzn?

It's an employer-provided laptop that runs Cortex XDR. I don't reckon that Cortex XDR would be the problem though, because my prior laptop had Cortex XDR as well and it ran without any issues.
